Al-Jazeera Video: Libya revolt: Tobruk

"Libyan troops forced rebels to retreat overnight from the outskirts of the oil town of Ras Lanuf, pushing the front line eastwards, and the rebel council's chief said more volunteers were ready to fight.

The front line now stands between the rebel-held town of Uqaylah and Ras Lanuf, where oil storage tanks were hit during Friday's fighting. Rebels blamed an air strike but the government denied hitting the oil plant.
